BONE VIBRATION SOUND SEAT

摘要

In a seat, a bass acoustic vibration transmission section and a treble acoustic vibration transmission section are arranged distinctively with respect to a seat occupant, such that those two acoustic vibration transmission sections are disposed independently of each other, thereby achieving both of the following two effects: an acoustic performance worthy of acoustic seat; and a seating comfort essentially required as a seat. A vibration conduction unit is provided, which comprises a combination of: one bass speaker; a support plate to which that one bass speaker is secured; and a network cushion member of three-dimensional structure arranged on an anterior surface of the support plate. Such vibration conduction unit is disposed and accommodated in a cut-out region defined in a seat padding to a predetermined extent of covering an area of seat back which corresponds to a lumbar part of seat occupant, whereas on the other hand, a pair of treble speakers are respectively provided in a pair of local areas of the seat padding which correspond respectively to left-side and right-side shoulder portions of seat back, such that each of those two local areas of seat padding has an opening defined therein, wherein the opening lies anteriorly of an output side of each of the two treble speakers.
